SCRAP-BUNDLING MACHINE.

Specification of Letters Patent.

Patented' Oct. 25, 1921.

Application filed March 29, 1920. Serial No. 369534.

To all whom it may concern Be it known that I, JAMES R. Con, a citizen of the United States, residing at VVaterbury, county of New Haven, State of Connecticut, have invented a certain new and useful Improvement in Scrap-Bundling Machines, of which the following is a full, clear, and exact description.

My invention relates to improvements in scrap bundling machines for forming metal scrap into compact bundles, and has for its object to provide an apparatus, with which the forming of bales is eXpedited so that more work can -be done in a given time. It further has for its object to provide a machine from which the bundles or cabbages are mechanically removed from the compression chamber. It further has for its object to provide a machine having a plurality of loading containers or baskets into some of which charges can be introduced while the material within another is being compressed. It further has for its object to provide means for moving a loaded Compartment into alinement with the first compression plunger. It further has for its object to provide an apparatus in which the' mechanism for actuating the compression plungers is locked when a container is notin alinement therewith. i

The following is a description of the ;apparatus embodying my invention, reference being had to the accompanying drawings, in which, t

F igure 1 shows a front elevation of the apparatus, two of three receiving containers being cut away;

Fig. 2 is an end elevation of the same showing one of the receiving containers in section; i i

Fig. 3 is an enlarged View showing parts parts in section to bring outcertain details;

F ig. 4 is a horizontal sectional View on the line 4-4, Fig. 3;

Fig. 5 is a sectional View on the line 5-5, Fi 3;

ig. 6 is a sectional View on the line 6--6, Fig. 5;

Fig. 7 is a sectional view on the line 5-6 Fig. 3 with the vertical plunger depressed and the horizontal compression plunger in compressing position;

Fig. 8 is a similar view with the blocking plunger retracted and the horizontal compression plunger fully advanced beyond the path of the blocking plunger;

F ig. 9 is a diagrammatic view showing the charging receptacles, a valve controlling mechanism and an interlock between the two; V

Fig. 10 is a detail showing the head of the interlock in a position to release the valve controlling mechanism; and,

Fig. 11 shows the valve controlling mechanism unlocked and partially moved.

Referring more particularly to the drawings, 1 1 l are three containers rigidly connected together and mounted so as to rotate about one of the uprights 2 2' of a hydraulic ram having the vertical plunger 3 and the well known cylinder 4 for actuating the same in both directions. These containers, 1, 1, 1 are so mounted that they can be successively swung over an opening 5 in a flooring 6, this opening being the mouth of a compression chamber 7, Fig. 5. Each of these containers is provided with a lever 8 pivoted thereto at 9 so as Swing in a vertical plane which passes substantially through the aXis of the support 2 around which the containers 1, 1, l revolve. The two opposite side walls of the compression chamber are-integral with the bottom 10 thereof, as shown in Fig. 6. One of the other sides is formed by a movable crossslide or blocking plunger 11 actuated by the hydraulic cylinder 11' which plunger, when in position, as shown in F ig. 7 separates the compression chamber from a discharge opening 12, being held from lateral movement by upright portions 13 integral with the base of the compression chamber. The opposite wall of the compression chamber, when open to its full eXtent, is formed by the front end 14 of a horizontal plunger 15 actuated by a hydraulic cylinder 16. The apparatus is provided with sequence valves, such as are commonly used for opercylinders through suitable piping by the sequence valves.

to be compressed.

3 downward into that container. This pres sure is continued until the plunger 3 reaches the position shown in dotted lines in Fig. 5, where it is then held. A further turn of the shaft 18 causes the valves controlling the cylinder 16 to operate so that the pressure in that cylinder :forces the 'plunger 15 underneath the plunger 3 to the position shown in Fig. 7 compressing the scrap previously partially compressed by the plunger 3 into the small space 7', shown in Fig. 7 A further operation of the shaft 18 causes the pisten 15 to stop, whereupon a further operation of the shaft 18 causes the cylinder 11' to retract the plunger 11 so as to open one side of the compression chamber 7 Thereupon a further operation of the .shaftlS causes the plunger 15 to still further advance until it goes beyond the path of the plunger 11, forcing the eompressed bundle or cabbage out into the discharge opening 12. ;A further operation of the ,shaft 18 causes the plungers 3 and 15 to 'retreat' to their initial positions and causes the plunger 11 to advance to its initial position, wherein it closes one end of the compressonchamber. Dur ng this operation theattendants have been filling one or both of the other containers 1, 1 and after the plungers have resumed their initial position the containers are rotated by means of the levers 8, liftedto horizontal position,

so that the next container is brought beneath the plunger 3,- whereupon the cycle already described is repeated,

In order to avoid accident and the damage 'which would result if the plunger 3 were lowered at a time when none of the containers' 1, 1, 1 was in exact alinement with it and the compression chamber, I prcvide each container with a lateral extension or fiange 21 near its bottom and form in each such lateral extension a cam recess 22. I

then mount upon the platform a bell-crank lever 23, having a nose 24 adapted to enter the recesses 22 when their containers are properly positioned. "This bell-crank lever is provided with a spring 25, which tends to hold the nose 24 against the cam surface 21 andto force it to enter the recess 22 when that recess is in alinement therewith. The free end of .the'bell-crank lever is connected by a rod 26 to a lever 27 pivoted at 28 and having pivoted to the other end thereof a looking pin '29, which is adapted to enter a recess 30 in a plate 31 upon the Shitft 18. The result of this is that whenever a container 1 is not quite in alinement with the compression chamber and the plun ..ger 3, the nose 24 of the bell-crank lever 23 will' be held in outward position' so that the looking pin 29 will be held within the lock- "ing recess 30 in the disk 31, thus preventing ,the shaft 18 from turning so as to operate the valves. When the recess 30 is moved opposite the locking pin 29, the plungers 3 and 15 are retracted and the plunger 11 is in its locking position'ready for the beginning of a compression cycle. This being the case, the interlocking means above 'described insures the correct positioning of the containers before the valves can be operated so as to cause the'apparatus to begin its compression cycle and removes the danger' 'of alinement with said chamber, a vertical plunger adapted to enterany one of said containers when it is in alinement therewith and with said chamber, and force the contents out of the movable container and into the stationary compression chamber, and a horizontal plunger having its aXis in line with said chamber and adapted to move toward and from one-end -thereof to compress the material therein, and hydraulic cylinders for actuatng said plungers.

In a bundling machine, the' combination of .a base having a stationary open-topped compression chamber, a plur'ality of' augularly displaced bottomless containers revoluble about a vertical azis into *and out ofalinement with said chamber, a vertical plunger adapted to enter anyone of said containers, when it is in alinement therewith and with said chamber and force the contents out of the movable container and into the stationary compression chamber and a horizontal plunger having 'its aXis in line i with said chamber and adapted to movetoward and from one end thereof to compress the materialtherein, hydraulic cylinders for actuating said plunger-s, means for means when said containers are outof alinement' with such plunger.
